摘要
维生素A是各种饲料中不可缺少的微量有机化合物。由于植物饲料中不含V_A,饲料中的V_A主要是补加的V_A醋酸酯,动物饲料中的V_A也主要以酯的形式存在。因此,建立一个快速精确的分析饲料中V_A醋酸酯的方法是很有必要的。
Vitamin A acetate in compounded feeds,concentrate supplements and feed additives was released from the feeds or ceils after supersonic treatment in the presence of 0.01mol/L hydrochloric acid and alcohol and measured by HPLC.The operation conditions were μ-Bondapak C18 Column,methanol: water (95:5,v / v) mobile phase and UV-326nm detector.The recovery and coefficients of variation were 95% and 0.97-3.5% respectively.
